National Instruments CAL-4300B Calibration Accessory
The CAL-4300B (Part number 781852-01) is the National Instruments Calibration Accessory used with the TB-4300B terminal block. It helps ensure that the performance and accuracy of the TB-4300B are according to specifications as outlined by National Instruments.
The CAL-4300B allows verification and calibration procedures through the appropriate wiring connection to the TB-4300B terminal block. It secures rapid implementation during this calibration process; thus, it provides accurate electrical measures and, meanwhile, adjustments. The assembly process will need the CAL-4300B to fit with and seat the TB-4300B in a manner so as to ensure a stable and reliable interface. It is an important spare for an engineer or technician who wants to make sure that this terminal block will meet the specifications both in performance and in safety.
The calibration accessory is designed to operate with the Fluke 5700A precision calibrator or equivalent and digital multimeters like the NI 4070, or similar 6½ digit multiranging DMMs. The CAL-4300B has the capability to address the input conditions required for stable electrical environments, such as tight controls over temperature and humidity. From providing very accurate voltage attenuation ratio measurements highly essential to establish the integrity of TB-4300B in data acquisition and control systems, the various diagnostic and verification activities it performs continue to expand.
Manufactured to exacting standards, the CAL-4300B provides a proven solution for laboratories, production facilities, and field application where precise calibration is paramount. Robust construction is a factor for longevity and repeatability during rigorous calibration routines. For repeatable high-accuracy calibration that may be needed for test and measurement, industrial automation, and control systems support at any time, the TB-4300B terminal block can always be used for more demanding purposes ahead.
